Just went to add this to the barnacles guide and cannot find any info for it so wondering if you could help @nzshells? I have the location as Kermadecs but not sure if Aupourian, cookarian etc and what tidal zone :) Naturally if it lurks in my area I will try and find it when I get home :)

As far as I know it has not been recorded from mainland NZ before, but it is known from the Kermadec Islands, Lord Howe Island, and eastern Australia.
Given those localities it is entirely possible that it may occur in the far north.
So yes, be on the look-out for it!

P.S. Intertidal

This species has an interesting distribution. It was described from a single specimen from South Africa, where it appears to be rare. Two small populations have been reported from Western Australia but it is thought to have been introduced there (the paper suggested this may have been from eastern Australia in ballast water). I haven't been able to find any records of it from mainland New Zealand. It has been known from the Kermadecs since the early 1900s.

Its biology has been quite intensively studied in eastern Australia.
